Assessment of fetal cardiac functions in pregnant women with anemia: prospective, case-control study.

OBJECTIVE: To compare the fetal cardiac functions between pregnant women with iron deficiency anemia (IDA) and healthy controls. METHODS: This single-center, prospective, case-control study was conducted at a tertiary hospital. A total of 150 patients, including 50 patients with IDA and 100 healthy pregnant women at 30-34 weeks of gestation, were included in the study. Of the patients with anemia, 20 had mild anemia, 18 had moderate anemia, and 12 had severe anemia. Pulsed-wave Doppler, M-mode, and tissue Doppler imaging (TDI) were performed to evaluate fetal cardiac functions. The fetal cardiac score was calculated using the systolic, diastolic, and global hemodynamic function parameters. RESULTS: The myocardial performance index and isovolumetric relaxation time were significantly higher in the IDA group than the control group, while isovolumetric contraction time was similar. Among the tricuspid and mitral valve diastolic parameters, the E, A, and E/A values were significantly lower in the IDA group (p<0.001). Mitral and tricuspid annular plane systolic excursions (MAPSE and TAPSE, respectively) were significantly lower in the IDA group (p<0.001). The IDA group also had significantly lower values for the TDI parameters, mitral and tricuspid E', A', S', E'/A' and a significantly higher E/E' ratio (p<0.001). Upon examination of anemia subgroups, a significant decrease was observed in the tricuspid and mitral A, E, and E/A in those with severe anemia (p<0.001). M-mode Doppler analysis revealed significantly lower TAPSE and MAPSE in the patient group with severe anemia. According to the subgroup comparison of TDI findings, the patients with severe anemia had significantly lower tricuspid and mitral E', A', S' and E'/A' (p<0.001) values and a significantly higher E/E' ratio (p<0.001). The fetal cardiac score was significantly higher in the maternal IDA group compared to the control group. A significant negative correlation was found between maternal hemoglobin level and fetal cardiac score (p<0.001). CONCLUSIONS: There may be changes in the systolic and diastolic cardiac functions of the fetuses of pregnant women with IDA. This study showed an increased E/E' ratio in the fetuses of pregnant women with IDA, suggesting a decrease in fetal heart maturation. Within the IDA group, fetal cardiac functions were more affected in those with severe anemia. This article is protected by copyright. All rights reserved.

Alternative Payment Models and Working with Payers-Key Considerations for Advancing Population Health Goals and Achieving Child Health Equity.

This article summarizes approaches to achieving value-based care in Pediatrics, providing a framework for understanding the continuum of models from fee-for-service to advanced alternative payment models. We present key examples of how alternative payment models have been developed and applied at the federal level within Medicare through the work of the Centers for Medicare and Medicaid Services (CMS) and the Center for Medicaid and Medicaid Innovation (CMMI). We further describe key lessons learned and opportunities to adapt value-based payment models to promote whole child health and equity. Finally, we summarize policy considerations and challenges in achieving accountability and aligning financial incentives for children's health within a complex payer landscape.

How to manage renal masses in kidney transplant recipients? A collaborative review by the EAU-YAU kidney transplantation and renal cancer working groups.

INTRODUCTION: Kidney transplant (KT) recipients have a four-times higher risk of renal malignancies compared to general population. As these patients frequently harbor bilateral or multifocal tumors, the management of renal masses is still under debate. OBJECTIVE: To explore the current management of the native kidney masses in KT patients. ACQUISITION OF EVIDENCE: We performed a literature search on MEDLINE/PubMed database. A number of 34 studies were included in the present review. SYNTHESIS OF EVIDENCE: In frail patients with renal masses below 3 cm, active surveillance is a feasible alternative. Nephron-sparing surgery is not justified for masses in the native kidney. Radical nephrectomy is the standard treatment for post-transplant renal tumors of the native kidneys in KT recipients, with laparoscopic techniques leading to significantly less perioperative complication rates as compared to the open approach. Concurrent bilateral native nephrectomy at the time of transplantation can be considered in patients with renal mass and polycystic kidney disease, especially if no residual urinary output is present. Patients with localized disease and successful radical nephrectomy do not require immunosuppression adjustment. In metastatic cases, mTOR agents can ensure efficient antitumoral response, while maintaining proper immunosuppression in order to protect the graft. CONCLUSIONS: Post-transplant renal cancer of the native kidneys is a frequent occurrence. Radical nephrectomy is most frequently performed for localized renal masses. A standardized and widely-approved screening strategy for malignancies of native renal units is yet to be implemented.

Immune-inflammatory-nutritional status predicts oncologic outcomes after radical cystectomy for urothelial carcinoma of bladder.

OBJECTIVE: To perform the first investigation of the role of immune-inflammatory-nutritional status (INS) on oncological outcomes in patients undergoing open radical cystectomy (ORC) for urothelial carcinoma (UC). MATERIALS AND METHODS: The records of consecutive patients who underwent ORC for non-metastatic bladder cancer between 2009 and 2020 were retrospectively analyzed. Neoadjuvant chemotherapy, non-urothelial tumor biology, and absence of oncological follow-up were exclusion criteria. Systemic immune-inflammatory index (SII) and Prognostic Nutritional Index (PNI) values were calculated and optimal cut-off values for these were used to designate four subgroups: "high SII-high PNI", "low SII-high PNI", "low SII-low PNI", and "high SII-low PNI". The Low SII-high PNI INS group had best overall survival (OS) rate while the remainder were included in non-favorable INS group. Survival curves were constructed, and a multivariate Cox regression model was used for OS and recurrence-free survival (RFS). RESULTS: After exclusions, the final cohort size was 173 patients. The mean age was 64.31 ± 8.35 and median follow-up was 21 (IQR: 9-58) months. Optimal cut-off values for SII and PNI were 1216 and 47, respectively. The favorable INS group (low SII-high PNI, n = 89) had the best OS rate (62.9%). Multivariate Cox regression analysis indicated that non-favorable INS (n = 84) was a worse independent prognostic factor for OS (HR: 1.509, 95%CI: 1.104-3.145, p = 0.001) and RFS (HR: 1.285; 95%CI: 1.009-1.636, p = 0.042). CONCLUSION: Preoperative assessment of INS may be a useful prognostic panel for OS and RFS in patients who had ORC for UC.

Evaluation of antibody response of sheep to foot-and-mouth disease vaccine prepared by using different MontanideTM oil adjuvants.

Despite the widespread use of the conventional inactivated foot-and-mouth disease (FMD) vaccine, its immunogenicity is poor and the duration of its protection is short. In this study, humoral response to commercial ready-to-use MontanideTM ISA 201 VG and MontanideTM ISA 61 VG oil adjuvants and a common adjuvant MontanideTM ISA 206 VG developed by Seppic Inc., were evaluated for FMD antigens in sheep and double oil emulsion (w/o/w) formulations of MontanideTM ISA 201 and 206 and single oil emulsion (w/o) of MontanideTM ISA 61 have been prepared by using current FMDV antigens (O/TUR/07, A/ASIA/G-VII, A/TUR/16 and ASIA/ TUR/15). The animals (n=48) were vaccinated subcutaneously with formulations and five sheep were maintained as an unvaccinated control group. Blood samples were taken at day 0, 7, 14, 21, 28, 60, 90, 120 and 150. Virus neutralization and liquid phase blocking ELISA tests were used to compare antibody response to vaccines prepared by using different MontanideTM mineral oils. The results showed that vaccines prepared by using MontanideTM ISA 61 and 201 gave better antibody response to FMD antigens than MontanideTM ISA 206 formulation, although results were not statistically significant for certain days of sampling. Moreover, the overall type O antibody response of MontanideTM ISA 201 was found to be superior to MontanideTM ISA 61.

Association between basal proteinuria levels and pregnancy outcomes in familial Mediterranean fever.

We aimed to investigate whether proteinuria in the first trimester of pregnancy in Familial Mediterranean fever (FMF) patients has an impact on pregnancy outcome and perinatal and neonatal outcome of pregnancies. A total of 66 pregnant with FMF were compared with healthy controls at the same gestational weeks. Patients with FMF had a higher antenatal hospitalisation rate (34.8% vs. 6.1%, respectively, p < .01) and higher rate of 2 or more miscarriages. FMF patients with or without obstetric complications also had a similar amount of 24-h urine proteinuria in the first trimester. Patients on colchicine therapy during pregnancy had more frequent attacks in pregnancy (59.3% vs. 18.2%, respectively, p: .012). The rates of preeclampsia, preterm delivery, foetal anomalies, small for gestation age neonates and primary caesarean rate were similar between groups. In conclusion; FMF had no significant impact on pregnancy. Neither attacks in pregnancy nor basal proteinuria were associated with adverse outcomes.Impact statementWhat is already known on this subject? Familial Mediterranean fever (FMF) is an autosomal recessive disease characterised by inflammation of the serosal, synovial and cutaneous tissues with recurrent attacks. One of the most serious complications of FMF is amyloidosis that can cause end-stage renal disease. Outcomes of FMF on pregnancy have been analysed by only few studies. Amyloidosis based on the initial renal function may adversely affect pregnancies. It has been reported that FMF patients with renal amyloidosis may suffer pregnancy complications to a greater extent.What do the results of this study add? There have been few studies on the correlation between FMF, proteinuria and pregnancy outcomes. In our study we found that FMF had no significant impact on pregnancy. Neither attacks in pregnancy nor basal proteinuria were associated with adverse outcomes.What are the implications of these findings for clinical practice and/or further research? Our study suggested that FMF had no relationship between pregnancy outcomes. However, our study population is relatively small. It will contribute to comprehensive studies involving a larger population. Future studies should be performed to investigate the effects of basal proteinuria in pregnancy with FMF.

No ischemia technique, parenchymal preservation and age are the most important determinants of renal function after partial nephrectomy.

OBJECTIVE: The aim of the present study was to compare the outcomes of Off-Clamp to On -Clamp approach during robot-assisted partial nephrectomy (RAPN). MATERIEL AND METHODS: Retrospective study of 940 patients who underwent a RAPN between 2007 and 2015 for cT1a tumors using On-Clamp or Off-Clamp approaches. Patient with solitary kidney or multifocal were excluded. Overall, 103 patients underwent Off-Clamp approach and 37 patients On-Clamp approach. We matched the patients in terms of tumor size, Charlson comorbidity index and R.E.N.A.L. score. At all, 309 patients from the On-Clamp were matched to the Off-Clamp group. We compared the clinic-pathological characteristics, perioperative morbidity and late functional outcomes between the 2 propensity score matched groups. Limitation included retrospective analysis. RESULTS: After matching, there were no difference in clinic-pathological characteristics in terms of gender, age, race, body mass index, Charlson comorbidity index, American Society of Anesthesiologists score, baseline estimated glomerular filtration rate (e-GFR), tumor size, R.E.N.A.L. score complexity, hilar (H) location between the 2 groups. Regarding perioperative outcomes; while operative time (P=0,4), estimated blood loss (P=0,28), Clavien grade III-IV complications (P=0,8) surgical reoperation (P=1), 30-day readmission (P=1), positive surgical margin (5,5% vs. 5,8%, P=0,9) were comparable between the 2 groups, there were significant difference in excisional volume loss (median, 7,08 vs. 3,51cm3, P<0,01), e-GFR decline (median, -9,7 vs. -2,2ml/min/1,73 m2, P<0,01), percent of e-GFR preservation (median, 87% vs. 97%, P<0,01), and CKD upstaging (36,5% vs. 23,3%, P=0,01), Off-Clamp approach (P=0,01), and age (P=0,02) were predictors of renal function preservation, whereas excisional volume loss (OR=1,035, CI 95% (1,015-1,06), P<0,01) predicted upstaging. CONCLUSION: RAPN for selected renal mass using Off-Clamp approach offered renal functional advantage over On-Clamp, without adding morbidities. While no ischemia technique was associated with less excisional volume loss, Off-Clamp approach, and age were independent predictors of renal function preservation. Clinical significance of these findings in various clinical settings will require further investigation.

Dual-comb mid-infrared spectroscopy with free-running oscillators and absolute optical calibration from a radio-frequency reference.

By using free-running independent femtosecond OPOs with a repetition-rate difference of 500 Hz we demonstrate methane absorption spectroscopy with spectral coverage simultaneously spanning the methane P, Q and R branches and with a resolution of 0.5 cm-1. Absolute optical frequency calibration with an accuracy of 0.25 cm-1 (0.27 nm) is achieved from simultaneous repetition-rate and carrier-envelope-offset frequency measurements, without the need for any optical reference. The calibration technique allows registration and averaging of consecutively acquired dual-comb spectra, leading to a high quality and low-noise absorbance measurement in good agreement with the HITRAN database.

P wave and QT dispersion in familial mediterranean fever.

OBJECTIVE: Familial mediterranean fever (FMF) is the most common auto-inflammatory disease that is characterized by recurrent, self-limited attacks of fever and serous membrane inflammation. Patients with inflammatory rheumatic diseases are considered to have a raised cardiovascular diseases risk. The aim of this study was to investigate; by means of P wave dispersion (Pd) and QT dispersion (QTd) parameters detected by simple standard electrocardiogram (ECG), atrial and ventricular repolarization changes in pregnant women with and without FMF. PATIENTS AND METHODS: In this case-control study including 37 pregnant women with FMF who already put on colchicine treatment and 40 healthy, uncomplicated pregnancy cases, were prospectively assessed using 12-lead ECG and echocardiography. RESULTS: No differences in Pd and corrected QT values were found between the groups. Epicardial fat thickness values were significantly higher in the FMF group compared with the control group (p = 0.015). A positive correlation was found between FMF duration and epicardial fat thickness (r = 0.350, p = 0.042). CONCLUSIONS: Pd, a non-invasive marker of potential atrial arrhythmia and QT-d, a non-invasive marker of potentially lethal ventricular tachyarrhythmia, constitute a recent contribution to the field of noninvasive electrocardiology. Pd and QT-d values were not altered in pregnant women with FMF who already put on colchicine treatment, with no increased risk of atrial or ventricular arrhythmias indicated. Colchicine may have a cardio-protective effect beyond the effect mediated through suppression of inflammation.

Anterior placenta previa is associated with increased umbilical cord blood hematocrit concenrations.

OBJECTIVE: We aimed to evaluate the umbilical cord blood (CB) hematocrit (Hct) levels in women with anterior located placenta previa (PP). METHODS: This is a prospective case-control study performed in a tertiary level maternity hospital. Thirty seven pregnant women diagnosed with anterior PP (study group) and 37 women without PP (control group) included into the study. Groups were matched with regard to age, gestational age, and fetal gender. All women underwent Cesarean section. Umbilical CB Hct levels of the newborns were measured. Demographics, operative features, and neonatal outcomes were recorded. RESULTS: Umbilical CB Hct levels were statistically significantly higher in the PP patients compared with controls (p: 52.6±5.0 vs. 47.5±5.0, p < 0.001). Preoperative maternal hemoglobin (Hgb) and Hct levels were similar in the two groups. However, postoperative Hb and Hct levels were significantly lower in the study group (p: 0.003, p < 0.001, respectively). Intraoperative complication rates were higher in this group. Neonatal Apgar scores were lower and neonatal intensive care unit admission was more common in the PP group when compared with controls. CONCLUSION: We think that anterior PP is associated with increased umbilical CB Hct levels. Neonatologists should consider this condition in the infants born to mothers with anterior PP.

Preventive Services Use Among African American and Latino Adult Caregivers in South Los Angeles.

BACKGROUND: The burden of informal caregiving is significant and well-documented, yet the evidence is mixed as to whether being a caregiver presents an additional barrier to receiving recommended preventive care. OBJECTIVES: To determine whether (1) caregivers compared with noncaregivers were less likely to receive preventive health services; and (2) higher intensity caregivers were less likely to receive preventive health services than lower intensity caregivers. RESEARCH DESIGN, SUBJECTS, AND MEASURES: Data were from a telephone survey of Latino and African American adults 50 years or older in South Los Angeles (n=702). Outcomes were flu vaccination, pneumococcal vaccination, and colorectal cancer screening. Logistic regression models adjusted for predisposing, enabling, and need factors according to the Andersen Model of Access to Health Care for Low-income Populations. RESULTS: Caregiver type (eg, adult child, nonrelated) was associated with varying odds of receiving a preventive service. Caregivers had lower odds than noncaregivers of receiving preventive services although odds of receiving a flu vaccination improved slightly for caregivers of persons with memory loss compared with other caregivers. More weekly caregiving hours was associated with higher odds of receiving flu vaccination (adjusted odds ratios, 1.1; 95% confidence interval=1.0, 1.1) or colorectal cancer screening (adjusted odds ratios, 1.1; 95% confidence interval=1.0, 1.1). Caregivers and noncaregivers age 65 and older or with chronic conditions were more likely to receive vaccinations. CONCLUSIONS: Preventive service use was influenced by characteristics of the caregiving situation. An opportunity may exist to leverage care recipients' ongoing contact with health care providers to increase caregivers' own access to preventive services.

Effects of selenium on ischaemia-reperfusion injury in a rat testis model.

Selenium is shown to have beneficial effects on ischaemia-reperfusion (IR) injury. Our aim was to assess the effects of selenium on IR-induced testicular damage in terms of biochemical and histopathological evaluation. A total of 32 rats were randomised into four groups: control, IR, IR + selenium (IR + S) and S. Detorsion was applied after 3 h of torsion. Testicular tissue superoxide dismutase (SOD), glutathione (GSH), malondialdehyde (MDA), total antioxidant capacity (TAC) and DNA fragmentation levels were determined. Testicular tissue samples were examined by histopathological examination and terminal deoxynucleotidyl transferase dUTP nick end-labelling staining. The control, IR and IR + S groups had higher SOD values compared with the S group; SOD levels of the control and IR + S groups were higher than those of the IR group (P < 0.05). Further, MDA levels of the IR group were higher than those in the other three groups (P < 0.05). The IR group revealed lower TAC levels than the three groups (P < 0.05 for all). GSH levels of the IR group were significantly lower than those in the other three groups (P < 0.05 for all). In contrast, GSH levels of the IR + S group increased compared with those of the S group. The IR group had more DNA fragmentation than the control and S groups (P < 0.05). It is concluded that selenium possibly reduces oxidative stress and apoptosis caused by testicular IR injury in rats. The testicular protective effect of selenium appears to be mediated through its anti-apoptotic and antioxidative effects. However, selenium does not affect DNA fragmentation.

Electronic clinical laboratory test results data tables: lessons from Mini-Sentinel.

PURPOSE: Developing electronic clinical data into a common data model posed substantial challenges unique from those encountered with administrative data. We present here the design, implementation, and use of the Mini-Sentinel Distributed Database laboratory results table (LRT). METHODS: We developed the LRT and guided Mini-Sentinel data partners (DPs) in populating it from their source data. Data sources included electronic health records and internal and contracted clinical laboratory systems databases. We employed the Logical Observation Identifiers, Names, and Codes (LOINC®) results reporting standards. We evaluated transformed results data using data checks and an iterative, ongoing characterization and harmonization process. RESULTS: Key LRT variables included test name, subcategory, specimen source, LOINC, patient location, specimen date and time, result unit, and unique person identifier. Selected blood and urine chemistry, hematology, coagulation, and influenza tests were included. Twelve DPs with outpatient test results participated; four also contributed inpatient test results. As of September 2013, the LRT included 385,516,239 laboratory test results; data are refreshed at least quarterly. LOINC availability and use varied across DP. Multiple data quality and content issues were identified and addressed. CONCLUSION: Developing the LRT brought together disparate data sources with no common coding structure. Clinical laboratory test results obtained during routine healthcare delivery are neither uniformly coded nor documented in a standardized manner. Applying a systematic approach with data harmonization efforts and ongoing oversight and management is necessary for a clinical laboratory results data table to remain valid and useful.

Changes in soil microbial biomass and aggregate stability under different land uses in the northeastern Turkey.

The characteristics of three neighboring soils from the NE of Turkey were evaluated in order to elucidate the effect of different land-use management on the soil aggregate stability and microbial biomass in Galyan-Atasu dam watershed. Three experimental sites corresponding to three land uses were selected. The first site is a hazelnut orchard (agriculture), the second site is a forest dominated by mature coniferous trees, and the third site is grassland. Soil aggregate stability values for the 1-2-mm aggregates increased from forest (lowest) to agriculture (highest) in the current study. The percentage of clay was highest in agriculture soils with 33.57 %, and overall stability values increased according to soil clay content. The lower aggregate stability in the forest soils probably reflects the highly silty texture soils with 11.95 % compared to agriculture and grassland. However, in our study, there were no significant correlations between aggregate stability and organic C concentrations either in cultivated or forested soils. Aggregate stability depended more on the organic matter content when the organic matter content was greater than 50 or 60 mg g(-1). Below that threshold, aggregate stability may be mainly related to clay content. Furthermore, the results confirmed that higher percentages of Cmic/Corg in agricultural soils are the result of more labile organic substrates maintained in the soil, allowing a higher microbial biomass C per unit of soil organic C. This work gives a better understanding of the relationships between land-use type and soil aggregation and allows to know the soil response to different types of management in humid environments.

Validity of diagnostic codes to identify cases of severe acute liver injury in the US Food and Drug Administration's Mini-Sentinel Distributed Database.

PURPOSE: The validity of International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) codes to identify diagnoses of severe acute liver injury (SALI) is not well known. We examined the positive predictive values (PPVs) of hospital ICD-9-CM diagnoses in identifying SALI among health plan members in the Mini-Sentinel Distributed Database (MSDD) for patients without liver/biliary disease and for those with chronic liver disease (CLD). METHODS: We selected random samples of members (149 without liver/biliary disease; 75 with CLD) with a principal hospital diagnosis suggestive of SALI (ICD-9-CM 570, 572.2, 572.4, 572.8, 573.3, 573.8, or V42.7) in the MSDD (2009-2010). Medical records were reviewed by hepatologists to confirm SALI events. PPVs of codes and code combinations for confirmed SALI were determined by CLD status. RESULTS: Among 105 members with available records and no liver/biliary disease, SALI was confirmed in 26 (PPV, 24.7%; 95%CI, 16.9-34.1%). Combined hospital diagnoses of acute hepatic necrosis (570) and liver disease sequelae (572.8) had high PPV (100%; 95%CI, 59.0-100%) and identified 7/26 (26.9%) events. Among 46 CLD members with available records, SALI was confirmed in 19 (PPV, 41.3%; 95%CI, 27.0-56.8%). Acute hepatic necrosis (570) or hepatorenal syndrome (572.4) plus any other SALI code had a PPV of 83.3% (95%CI, 51.6-97.9%) and identified 10/19 (52.6%) events. CONCLUSIONS: Most individual hospital ICD-9-CM diagnoses had low PPV for confirmed SALI events. Select code combinations had high PPV but did not capture all events.

The risks of small intestinal transplantation for the recipient: experimental results in young minipigs.

In a previous series of 36 small intestinal transplants in young minipigs, a monitoring system, based on a special transplantation model, clinical and histologic criteria has been worked out. The spontaneous evolution was observed and no attempt was made to save the animal when complications on the graft occurred. Most of the animals died. In the present series of 32 small intestinal transplants the monitoring system and explanation criteria are now tested. Twenty-three primarily successfully transplanted animals had complications of the graft, i.e., hemorrhagic infarction, deficient arterial circulation, or rejection. Only 1 of the 23 died before explanation could be done. Twenty-two were explanted according to the previously established criteria. Two died of complications not directly related to the graft, the other 20 animals survived for 1-5 mo. All 22 explanted grafts showed irreversible damages both macroscopically and on histologic examination. The present series confirms that early recognition of complications of the graft and timely removal with survival of the recipient animal is possible. This could be an important step forward to the clinical application of small intestinal transplantation in man.
